I'm pretty much at the end of my first year of sobriety. I've been thru most of everything once now -except Christmas, My Birthday, New Years. In that order. The last week of the year was always a doozy for me. But I'm quietly relaxing in my new apt. after a full days work -with my dog. Although I believe there's a difference between being alone and being lonely -I'd certainly be both without him. He is hairy awesomeness.
I think holidays and seasons do cause triggers for some but don't think of what you did -think of what you need to do. Look ahead to the 'other' side. The positive side.
